What is this job called? (asking for help3)

I am looking for a career on wall street and know what duties I would like to perform but am not positive on the title or keywords to search for.
Asking for a little help on pin-pointing this info.

My current job guess is "investment strategy researcher".

Job details in my head:
I would like to analyze as well as create short term (1 second to 3 week hold) trading strategies in any asset class.
I enjoy data mining, analytic research, creating statistical models, and backtesting.
